SPECIFICATION forming part of Letters Patent No. 440,058, dated November 4, 1890. Application filed September 29, 1890. Serial No. 366,476. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM J. PoN'ro, a citizen of the United States, residing at Hillsborough, in the county of Traill and State of North Dakota, have invented certain new and.

useful Improvements in Car-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. Y

Figure l is a side elevation showing a portion of the front of a railroad freight-car and the draw-head and present invention as applied in use. Fig. 2 is a longitudinal central section of the lower end of the rod that carries at its end the coupling-pin; Fig. 3, a detail in side elevation, showing the construction and arrangement of parts by which the coupling-pin rod may be held up when desired. Fig. 4 is a detail in section, showing how the lifting-rod is jointed to the shank at the eye that engages the upper end of the coupling-pin.

This invention is chiefly an improvement on the car-coupler shown in my patent, No. 413,549, of October 22, 1889; and the novelty consists in jointing the rod that operates the -coupling-pin, whereby in the movement of the cars in coupling there may be some flexibility.

I will now proceed to describe my invention in detail, reference being had to the accompanying drawings.

In the drawings, A denotes any ordinary freight-car, and B the draw-head centrally placed below it at the end, front, or rear, and through the usual spring b, having a certain amount of movement back and forth to prevent jar or breaking in coupling.

C is the bolt in the draw-head, to which is attached in the opening in the draw-head the supporting-plate o.

D is the coupling-pin, having on each side a iin d. The rod G, by which the couplingpin is raised, is connected with the pin by an eye g and passes through the ends of projections a, attached to the car. Excepting the spring b all the above is as in my said patent. Now, in order to 'allow a certain'degree of iiexibility at the lower end of the pinoperating rod G the shank h of the eye H is jointed to the lower end of this rod at G. This joint is made by socketing the shank at h and inserting the lower` end g of the rod G into it, as shown in Fig. 2, and then passing the pin or bolt I through the sides of the socket and end g. This bolt is at one side of the center, preferably, so as to give a better motion.

To aid in the operation of the joint, there is provided the bolt K, which lits into the central slot g in the lower end of the rod G. By

means of the spring L- about this bolt its` pointed lower end 7c is forced down into the shallow seat h2 in the socket h. By this means any trouble that could happen from a rigid connection between the coupling-pin and its lifting-rod is obviated. i

To enable the lifting-rod to be held up when it is desired to have the coupling-pin up out of the draw-head, there is provided on the top of the car the spring-actuated bolt M,

which is adapted to t into the notch g2 in` the rod. Thus this rod may easily be held up,

o r by withdrawing the bolt from the notch will be allowed to drop down.

It will be obvious that by means of the joint G and the structure above explained practically all the advantage of a single rod is obtained, because under all ordinary conditions of use this bar as a bar holds the pin vertical. coupling the car that the spring comes into use. Hence it is far preferable to a chain or other flexible connection of the lifting-rod with the coupling-pin on the shank of the eyebolt.

Having now described my invention, I claiml. In a car-coupler, the combination of the lifting-rod G and the eye H, joined to it at G in the manner described, and having within the joint the spring-actuated bolt with the coupling-pin D, in the manner and for the It is only under the 'condition of h in its upper end Vand. a seat 7L2,and the pin presence of twovwitnesses.
